Both paths use the same models (Claude, Codex, Gemini) and the same tools. The only difference is how you pay.

Tool & credit breakdown

Every tool has a fixed credit cost. Subscription tiers gate higher-tier tools by default — a credit pack unlocks all of them regardless of tier.

Frequently asked questions

Do I need a subscription to use 2ndOpinion?

No. Buy a credit pack ($5 for 100 credits, never subscribed) and use any tool — including the high-tier ones like Consensus Review and Bug Hunt. Bonus credits from a pack unlock all features. The credit cost itself is the throttle.

Do credits roll over?

Subscription credits reset each billing cycle. Credit packs never expire (valid for 1 year from purchase) and stack on top of your monthly subscription credits.

What happens when I run out of credits?

You'll get a 402 error on your next request with a one-click link to buy 100 more credits for $5. No subscription required.

Is there a free trial?

Yes — the Pro plan includes a 7-day free trial with 100 credits. Add your card during signup, try everything, cancel anytime before day 8 and you pay nothing. Or skip the trial entirely and just buy a $5 credit pack.

Can I switch plans?

Yes, upgrade or downgrade anytime from your dashboard. Changes take effect immediately.

What payment methods do you accept?

All major credit and debit cards via Stripe. We also support Apple Pay and Google Pay where available.

Can I cancel anytime?

Yes, no contracts. Cancel from the billing dashboard and your plan downgrades at the end of the current cycle. Credit packs are one-time purchases — nothing to cancel.
